摘要：

The production of a near-diffraction-limited single-lobed angle-switchable output beam from a broad-area diode laser with an intracavity spatial phase controller is demonstrated. This 100-mu-m-wide broad-area laser produces a 0.8-degrees full width at half maximum output beam at single-facet pulsed powers of > 300 mW. The spatial phase controller operates in two distinct modes (thermal and gain), providing beam scanning over 1.4-degrees and beam switching of 8-degrees. The phase controller also permits a dynamic study of the effect of wavefront tilt on device coupling and phasing.
